Chicken with Roasted Peppers and Salsa Verde

From a Serious Eats post that Anna sent along last week. Turned out pretty well, though it looks like my sauce didn't thicken quite as much as it was supposed to... and I burned my silicon tongs a bit roasting the peppers... but I really liked the flavor and spice of the poblanos. Strangely the recipe seems to be lacking instructions regarding the onions... I just cooked them until they were starting to brown.
